Internet-delivered Behaviour Therapy for Children and Adolescents With Tourette's Disorder

"The intervention consists of 10 modules/chapters for children/adolescents, delivered over 10. Each of the 10 modules includes age-appropriate texts, animations and exercises. The intervention is primarily based on ERP techniques. During the treatment, participants are instructed to practice suppressing their tics, this is known as 'response prevention'. Then, with the help of their caregiver/parent, the participant is instructed to provoke premonitory urges (a sensation usually felt before a tic is expressed), while still suppressing tics, which is known as 'exposure'.~The parent is provided with her/his own separate login to the internet platform, which consists of 10 separate modules/chapters. The parent intervention consists mainly of information regarding parent coping strategies, social support and functional analysis relating to tics. Both the child/adolescent and the parent have individual access to the same therapist."

"The active comparator is designed to match the experimental intervention in all aspects except for the module content (same platform, same treatment length, same therapist support etc.). The intervention consists mainly of psychoeducational information about TD/PTD and common comorbid conditions, and reviews the definition of tics, natural history, common presentations, prevalence, aetiology, risks and protective factors, strategies for describing tics to other people, among others. Problem-solving and development of expertise in tic disorders is emphasised. The intervention does not include any information on ERP or functional analysis and interventions.~As in the experimental intervention, the parent is provided with her/his own separate login to the internet platform. The parent intervention consists mainly of information regarding parent coping strategies and social support. Both the child and the parent have individual access to the same therapist."
